Abstract: <PICT:0402449/IV/1> <PICT:0402449/IV/2> A spinning-jet of the disc type for the production of artificial filaments, threads, yarns, and the like, has a thin face curved to resist distortion, and spinning orifices bored through the face in a direction parallel to the axis of the jet.  The jet face may be concave or convex.  The jet face may be curved by stamping, pressing, or spinning when the jet is being formed into the usual cup-like shape, or the jet may be submitted to the action of a fluid under very high pressure.  The orifices are bored after the formation of the curved face of the jet.  As shown in Fig. 2, the orifices 13 which are bored after the bulging of the jet face 10 are parallel to the axis of the jet and to each other.  As shown in Fig. 3, the face of the jet is curved inwardly.  The orifices 13 are bored parallel to the axis of the jet and not perpendicular to the jet face.  The construction of jet may be applied to dry or wet spinning processes and in particular to high speed dry spinning of cellulose acetate.

Abstract: 832,267. Applying travellers to textile spinning &c. rings. RINGLAUFFER G.m.b.H., O. May 20, 1957 [May 22, 1956], No. 15913/57. Class 120(3) A device for applying travellers to the rings of spinning &c. machines, of the kind in which travellers stored in a row and fed forwad by a spring are pressed singly on to a ring by a spring-influenced lever, is characterized by the provision firstly of two arms 1, 2, Fig. 3, pivoted to one another at 3 and normally kept apart by a spring 5, one of which is provided with a recess 6 to be fitted over the ring and the other with a presser member 19 for forcing the runners on to the ring, and secondly of a tubular storage 8 enclosing a supply of runners so that their openings will face the ring when the recess is fitted over the ring and arranged transversely of the plane of the arms and opening adjacent the recess. The travellers are held on a rod 11 in a tube 10 by a fin 12 engaging the gap between their ends on the rod is mounted a slidable piston 14 urged against the travellers by a spring 17, the other end of which engages a second piston having a lug which can be rotated to engage one of a series of notches in a slot in the tube 10, so as to adjust the tension of the spring according to the number of travellers in the storage. The travellers are thus urged against a piston 24 arranged on the opposite side of the recess 6 to slide on a rod 26 under the influence of a spring 28, the tension in which is adjustable. Owing to the relative strengths of the springs 17, 28, the piston 24 cannot be forced back by the travellers 9 and it takes up a position against the member 19 so that the latter is in line with the foremost traveller. Also the piston is positioned by a pin and slot so that the guide 29 is in line with the fin 12 and the gap in the stored travellers. With the arms in the open position, the device is applied to the ring so that the recess 6 fits over the flange 7<SP>1</SP> with the gap in the foremost traveller and the guide 29 opposite the flange. The arms are gripped together so that the pressermember 19 moves the foremost traveller on to the flange, the piston 23 being displaced as the traveller moves over an inclined part of the guide 29. The device is then tilted about the -edge of the ring so that the traveller is sprung over the flange. The arms consist of members of U-section providing a seating for the ends of the spring 9 and which can fit one within the other. The stored travellers may be lacquered together.

Title: Improvements relating to synchronisation of prime movers
IPC: H02P5/50
Filed: 1947-06-18
Abstract: 635,844. Automatic speed control systems. GENERAL MOTORS CORPORATION. June 18, 1947, No. 16056. Convention date, July 3, 1946. [Class 38 (iv)] A device for synchronizing the speed of prime movers comprises two rotatable members, one being driven by the prime mover to be synchronized and one by the other prime mover at the desired reference speed, one member having a simple contact which connects successively with three contacts on the other member during relative rotation, -such that a condenser is charged, and then discharged to actuate selectively a servo-mechanism to effect a corrective change of speed in the prime mover to be synchronized. In Fig. 2, rotating member 20 having a single projecting contact 20a, is rotated either directly, or by means of a tachogenerator and motor, by an aircraft engine. Condenser 18 is connected between earth and contact 20a by means of a slip ring. The other rotating member 19 has three contacts 23, 22 and 24 which are connected respectively to a battery 16 and relays 13 and 14 which selectively control a servomotor controlling the propeller pitch-change mechanism governing the speed of the aircraft engine. Member 19 is rotated at the desired reference speed which may be determined either by a speed controlled electric motor, or by another aircraft engine. If the speeds of member 19 and 20 depart from synchronism, contact 21 engages successively contacts 23, 22 and 24, condenser 18 thus becoming charged, and then discharged through one or other of the relays 13 or 14 according to the direction of the relative rotation. The arrangement is such that one charge on the condenser is sufficient to operate only the first relay circuit connected, thus energizing the pitch-controlling mechanism in a direction which assists synchronization. Specification 634,413 is referred to.
Patent GB-979564-A (GB)
Title: Production of titanium oxide
IPC: C01B35/00
Filed: 1963-04-24
Abstract: In the production of TiO2 by vapour phase oxidation of titanium tetrahalide TiX4, particularly TiCL4, a stream containing O2 and a stream containing TiX4 vapour are projected into the reaction zone, the linear velocity of the stream containing O2 being greater than that of the stream containing TiX4, and product TiO2 and Cl2 are withdrawn from the reaction zone in the same linear direction as the stream containing oxygen is projected into the reaction zone.  If VO is the linear velocity of the oxygen-containing stream, VT is the component of linear velocity of the TiX4 <PICT:0979564/C1/1> <PICT:0979564/C1/2> <PICT:0979564/C1/3> <PICT:0979564/C1/4> stream along the axis of oxygen flow and do is the diameter of the oxygen-containing stream, within 0.5 seconds of contact with the TiX4, the formula <FORM:0979564/C1/1> should have a numerical value greater than 50, preferably greater than 300.  An inert gas stream, for example N2, CO2, recycled produce gases, A, or particularly Cl2 may also be projected into the reaction zone having velocity VI such that <FORM:0979564/C1/2> is greater than 50, and preferably such that VI< 1/2 VO.  Suitable reactors are illustrated in Figs. 1, 3, 4. Fig. 1 shows a furnace A1 having a burner A fitted in its upper part and an outlet 7 at its base.  Burner A consists of concentric tubes 2, 3, 4 through which are introduced TiCl4, Cl2 and O2 respectively at feed rates correlated with the tube diameters to give a positive number between 300 and 20,000 as determined by the above formula. Product TiO2 and Cl2 formed in zone 30 are withdrawn in the direction indicated by the arrow from outlet 7.  Fig. 3 depicts burner B constructed of concentric tubes 10, 11, 12 through which are passed TiCl4, Cl2, O2 respectively. The tubes differ in length so that O2 jetting past slot 16 is circumscribed by inert gas, and this stream when passing slot 17 is enveloped by TiCl4, the three streams retaining their identity as they are projected into the reaction zone.  The reactant streams may also include an aluminium compound or a zirconium salt, and a silicon halide, particularly AlCl3 or ZrCl4, and SiCl4.  Other suitable additives include potassium salts and organo potassium compounds; metals and metal compounds of Groups Ia, Ib, IIa, IIb, particularly Mg, Ca, Cu, Zn in the metallic vapour state, as salts, or as organometallic compounds.  Fig. 4 illustrates a suitable reactor for the introduction, in separate streams, of oxygen, chlorine, chlorine + AlCl3, and TiCl4.  The oxygen-containing gas stream may be pure oxygen, air, or a mixture of oxygen with the products of combustion of a combustible gas, e.g. CO.  In the latter case the gas may be formed in situ before the introduction of TiX4. The temperature of the reaction zone is usually maintained between 750 DEG  and 1600 DEG  C.  The reactants may be preheated and the temperature of the inflowing oxygen stream is the same or greater than that of the TiX4 vapour stream. It is also preferred to pass inert gas along the furnace wall during the reaction.

Abstract: 515,361. Television. ELECTRIC &MUSICAL INDUSTRIES, Ltd., and BLUMLEIN. A. D. May 30, 1938, No. 16081. Addition to 458,585. [Class 40 (iii)] ' In a method of re-inserting direct-current components in a system using an "observing- device" and check signals having a switching- portion and a datum portion as described in the parent Specification, the signals with or without d.c. components, are fed at 201, Fig. 13, to an amplifier 204 capable of amplifying d.c. components, and correcting signals are derived from the output and fed back to the input to maintain the "black" level constant. The output is applied over phase-reversing valve 206 and delay network 207 to valve 208 to render it capable of conducting during the delayed sychronizing signal period, and this period coincides with the period of a datum level in the signal applied directly to valve 208 over 213; thus the output of valve 208 comprises only datum level signals which are rectified at 210, smoothed, and used to bias the amplifier 204 to maintain the datum level constant. In a modification, the amplifier 204, Fig. 14, has two inputs (e.g. two valves with a common output) and the output signal is delayed to render valve 214 conducting during synchronizing signal periods, thus altering the potential of the cathode of valve 215 to allow valve 215 to conduct during datum potentials to provide an output rectined at 210 and applied to the second input of amplifier 204. The delayed signal applied to valves 208 and 214 may be derived from the input of the amplifier 204. Specifications 422,906 and 464,828 are referred to.

Abstract: 685,652. Statistical apparatus. NATIONAL CASH REGISTER CO. June 28, 1950 [July 2, 1949], No. 16112/50. Class 106 (i). Apparatus for preparing a record member for effecting the control of statistical machines in accordance with recorded marks comprises a printing mechanism for applying the marks to a base record member, including an impression member for each of a plurality of index positions on the record member, a frame located beneath the impression members and supporting material carrying a marking fluid which includes a substance normally ineffective to influence an energy detecting device but which is activable to a higher energy level, sufficient to influence the detecting device, a platen located beneath the material for supporting the base record member, a selector member for selecting the impression member to be operated, and an operating device for causing the member to be operated, and an operating device for causing the member to depress the selected impression member and thereby apply the marking substance to the record base member at the desired index position. The marks representing data may be made with magnetic material such as iron oxide contained in an ink or a suitable binder, or a substance which may be made luminescent, for example a fluorescent or phosphorescent material such as willemite or anthracene contained in an ink or binder, and which once activated by exposure to light has an after-glow period, sufficient to enable the record card to be passed through the detecting apparatus. Fig. 2 shows a platen 20, two ribbons 22 and 23 which may be shifted to bring either type of ink into use and a plurality of impression printing members 24 one for each index point position in the card column. A selector member 28 is supported in a guide member 29 for movement, either manually or by some suitable apparatus above the members 24 and carries a spring-pressed plunger 34 which can be positioned over any desired one of the printing members 24. A depressing plate 30 is mounted between the free ends of the toggles 31 and 32 which are coupled to a push-rod 33. Movement of the push-rod 33 to the left will cause the toggles to be straightened to depress the plate 30 on to the plunger 34 which, in turn, depresses the selected member 24. The latter impresses the selected ribbon 22 or 23 on to the record card. When the records are to be read, the marks are first rendered active by means of a magnetic field or a suitable light source.
